Progress MS-03

Progress MS-03 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Progress MS-03 rather than just read about it. In short: Progress MS-03 (Russian: Прогресс МC-03), identified by NASA as Progress 64P, was a Progress spaceflight operated by Roscosmos to resupply the International Space Station (ISS). It was the first Progress MS to have an external compartment for releasing satellites.

Key takeaways

Progress MS-03 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Progress MS-03 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Progress MS-03 from memory before moving on to harder problems.

Reference excerpt

Progress MS-03 (Russian: Прогресс МC-03), identified by NASA as Progress 64P, was a Progress spaceflight operated by Roscosmos to resupply the International Space Station (ISS). It was the first Progress MS to have an external compartment for releasing satellites.

History Progress was the first cargo spacecraft to fly in space (1978), and also the first to bring freight back to Earth, thanks to a Raduga capsule. It was developed to supply the Salyut 6 space station and which was subsequently supply the crews of Salyut 7, Mir and from the International Space Station. It enabled space station crews to stay in space by bringing consumables (food, water, fuel, oxygen) and spare parts. The Progress-MS is a uncrewed freighter based on the Progress-M featuring improved avionics. This improved variant first launched on 21 December 2015. It has the following improvements:

New external compartment that enables it to deploy satellites. Each compartment can hold up to four launch containers. This Progress MS-03 flight features first usage. Enhanced redundancy thanks to the addition of a backup system of electrical motors for the docking and sealing mechanism. Improved Micrometeoroid (MMOD) protection with additional panels in the cargo compartment. Luch Russian relay satellites link capabilities enable telemetry and control even when not in direct view of ground radio stations. GNSS autonomous navigation enables real time determination of the status vector and orbital parameters dispensing with the need of ground station orbit determination. Real time relative navigation thanks to direct radio data exchange capabilities with the space station. New digital radio that enables enhanced TV camera view for the docking operations. The Ukrainian Chezara Kvant-V on board radio system and antenna/feeder system has been replaced with a Unified Command Telemetry System (UCTS). Replacement of the Kurs A with Kurs NA digital system.

Pre-launch The launch of Progress MS-03 was originally scheduled for on 30 April 2016, but was postponed as a result of an overall reshuffle of the flight manifest for the International Space Station. At the beginning of June 2016, the mission was rescheduled from 4 July to 17 July 2016.

Launch Progress MS-03 was launched on 16 July 2016 at 21:41:45 (UTC) on a Soyuz-U from the Baikonur Site 31/6 in Kazakhstan. At the time of launch, the International Space Station was flying at 420 km over Eastern Chad.

Docking The Progress MS-03 mission used the two-day, 34-orbit trip to the station instead of the currently available six-hour rendezvous profile. Progress MS-03 docked with the nadir docking port of the Pirs module on 19 July 2016 at 00:20 UTC.

Cargo The Progress MS-03 spacecraft delivered 2,425 kg of cargo and supplies to the International Space Station for the six members of the Expedition 48 crew. The following is a breakdown of cargo bound for the ISS:

Fuel: 705 kg Oxygen and Air: 50 kg Water: 420 kg Supplies for NASA: 22 kg Spare parts: 1,230 kg

Undocking and decay The Progress MS-03 cargo ship undocked from the Pirs, on 31 January 2017, at 14:25 UTC, Roskosmos announced. The three-minute braking maneuver was scheduled to begin at 17:34 UTC, followed by reentry into the dense atmosphere at 18:10 UTC. Surviving debris of the spacecraft were calculated to impact the Pacific Ocean at 18:24 UTC on the same day.

Worked examples

Example 1 — a first encounter with Progress MS-03

Start with the simplest possible case. Write down what Progress MS-03 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Progress MS-03 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Progress MS-03 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Progress MS-03

In research: Progress MS-03 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Progress MS-03 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Progress MS-03 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2016 in Russia, Progress (spacecraft) missions, Spacecraft launched by Soyuz-U rockets, so understanding it makes those chapters shorter.
In everyday life: Look for Progress MS-03 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
